A cardiac phantom model has been developed as an experimental and demonstrative tool for left atrial appendage (LAA) occlusion procedures. In patients with non-valvular atrial fibrillation, blood flow stagnation in the LAA, a small protrusion extending from the left atrium, can induce clot formation and subsequent stroke. The heart phantom offers a platform to evaluate the efficacy of occlusion devices and features highly-regulated pulsatile flow, the ability to modulate the base diameter and wall thickness of the LAA, and visualization of flow dynamics within the appendage.

A device to evaluate the quality of vibration transmission from a skull plate to the skull.

In response to increasing cases of tick-borne diseases, Dr. Adrianna Troyo and Dr. Tim Dye have sought an improved method of tick collection. They have asked us to design a mobile tick-collection device to replace the inefficient and labor-intensive current manual methods, which expose researchers to risk of being parasitized.

Current internal bone plate fixation methods waste valuable time alternating between automatic and manual drivers and cause surgeon frustration when relocating the head of the screw. We have developed a combined automatic/manual device for safe, efficient screw driving through all stages of the fixation process.

The Endotrach team has successfully developed an articulating probe utilizing bioimpedance spectroscopy to verify endotracheal tube placement after intubation.
